Variety.

m V. A. 2 latifolia Mill. (IV. Du Ham.,v\. p. 116.) has the leaflets broaderand shorter than those of the species. The spikes of flowersare shorter, and the flowers are always blue. It is a native of thesouth of France and Italy, and was known to Lobel and Bauhin .There are plants of it in the Cambridge Botanic Garden.

V. inclsa Lam., Mill. Ic., t. 275. figs. 1. and 2.; V. Negtindo Bot. Mag., t. 364.; is a native ofChina , where it grows to the height of 4 ft., and flowers from July to September. It was introducedin 1758, but is not common in green-houses.

Clerodendrum indrme R. Br.; Volkamferiain^rmis L., Jacq. Suppl ., 117. 4. f. 1.;and our jig. 1153. This shrub grows, withthe greatest vigour, against the wall in theHorticultural Society’s Garden, where ithas stbod since 1829; uninjured by any ofthe winters that have occurred during thatperiod.

Cleroddndrum speciosissimum Paxton’sMag. of Bot., 3. p. 217. A branching shrub,growing to the height of 4 ft., with an erectstem, and cordate pointed leaves, and flowersproduced in large spreading terminal pani-cles, of a vivid scarlet colour, and eachaveraging 2in. in length, tubular below,

I loo with a 5-parted spreading limb. The native

country of this plant is not stated ; but it is probably Japan . Messrs. Lucomband Pince of the Exeter Nursery received the plant from Belgium in 1835,and it flowered profusely in their nursery in August and September, 1836,and at Chatsworth in October of the same year. Mr. Paxton describes it asone of the finest plants which he has had the good fortune to figure; and asfar superior in beauty to any of the family to which it belongs. Messrs. Lucomband Pince have a very fine plant in the open border.

Durdnta, cydnea Hort. is a native of South America , and is generallyconsidered as a hothouse plant; but a plant has stood against the wallin the Horticultural Society’s Garden since 1833; and, though the shootsare killed back during the winter season, it always grows vigorously duringsummer, attaining nearly the height of the wall. 1154

Aloysia citriodom Or.; Ferbena triphylla L’Herit.; Lippi a citriodora Kunth,Bot. Mag., t. 367.; and our fig. 1154.; is a native of Chili, and has been inthe country since 1784. In dry soils, in the neighbourhood of London , itwill live in the open border for many years, without any protection, excepta little litter thrown about the roots; for, though frequently killed down tothe ground, it seldom fails to spring up with vigour the following spring,and cpntinue flowering the greater part of the summer. In the Chelsea Bo-tanic Garden, there is a plant against the wall, which in six years has attainedthe height of 10 ft., growing vigorously, and flowering freely. The leaves aregratefully fragrant when slightly bruised; and on this account, and also on thatof its small elegant whitish flowers, it well deserves a place in collections. Ofall those shrubs, Dr. Macculloch observes, “ which require the protection of agreen-house in England, the Ferbena ti'iphylla (Aloysia eitriodora) is that ofwhich the luxuriance is in Guernsey the most remarkable. Its miserablestinted growth, and bare woody stem, are well known to us. In Guernsey itthrives in exposed situations, and becomes a tree of 12 ft. or 18 ft. in height,spreading in a circle of equal diameter, and its long branches reaching downto the ground on all sides. Its growth is indeed so luxuriant, that it isnecessary to keep it from becoming troublesome by perpetual cutting : freshshoots, 14 ft. in length, resembling those of the osier willow, being annuallyproduced.” (Quayle's Jersey and Guernsey, Appendix , p. 341.) It is also com-monly said that this shrub attains a large size in the Isle of Jersey; but awriter in the Gardener's Magazine, vol. xii. p. 551., says that he expected tosee it generally cultivated, but that the only plant he saw in the island wasone in the garden of a nurseryman, and that not of extraordinary size. Thenurseryman, however, told him there were trees- in the island with steins asthick as his wrist, and proportionably high.
